Kali Linux

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security Ltd. Mati Aharoni and Devon Kearns of Offensive Security developed it by rewriting BackTrack, their previous forensics Linux distribution.^[1]

Kali is preinstalled with numerous penetration-testing programs, including nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper (apassword cracker), and Aircrack-ng (a software suite for penetration-testing wireless LANs).^[2] Users may run Kali Linux from a hard disk, live CD, or live USB. It is a supported platform of the Metasploit Project's Metasploit Framework, a tool for developing and executing security exploits.^[2]

Kali is distributed in 32- and 64-bit images for use on hosts based on the x86 instruction set, as well as an image for the ARM architecture for use on the Raspberry Pi computer and on Samsung's ARM Chromebook.^[3]
